What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

A multifaceted model of Entamoeba histolytica KERP2 regulating gene expression and host cell responsesNature communications · 2026
Summary (written by the submitters)
KERP2 is a secreted parasitic factor in Entamoeba histolytica that interacts with host colon epithelial cells, potentially contributing to pathogenesis. To investigate its influence on host gene expression, RNA-seq was performed on Caco-2 cells co-cultured with HA-KERP2-overexpressing E. histolytica (HA-KERP2), psAP-KERP2gs (partial KERP2 knockdown), or wild-type G3 strains, alongside untreated controls.
Read the full summary ↓
Differential expression analysis identified upregulation of key pro-inflammatory mediators (IL1B, IL36G), signaling adapters (SLA), and heme-related genes (HRG) in HA-KERP2-treated cells, while cytoskeletal regulators (CYTIP, MYOCD), stress-response factor (NUPR1), and solute transporters (SLC15A3) were downregulated. In contrast, psAP-KERP2gs-treated cells exhibited increased expression of extracellular matrix components (TNC), contractility regulators (MYL7), and metabolic enzymes (CYP4B1), while genes involved in cilia function (CFAP43), solute transport (SLC2A12), and the pentose phosphate pathway (TKTL1) were downregulated.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE290901_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1230282 and SRA study SRP567183. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
